Figure 1From: Flow-volume loops derived from three-dimensional echocardiography: a novel approach to the assessment of left ventricular hemodynamics Analysis of LV volumes using 3D-echocardiography. In the selected LV image (upper left), the algorithm (4D LV-Analysis CRT 1.0, TomTec) provides semi-automated delineation of the endocardial border (upper right). By superposition of LV contours from 6 insonation planes (lower left) in 3D space, the LV volumes are calculated and the graphic presentation of LV volume changes in time can be obtained (lower right).Back to article page
